P. aeruginosa is a microorganism found in the environment that, if ingested, can cause life-threatening infection in immunocompromised individuals. P. aeruginosa infections are generally limited to hospital settings.

The products are distributed nationwide through Amazon. The company has not received a direct complaint from using their products.

The importance of this issue is that P. aeruginosa is a facultative pathogenic bacterium, and it is a critical question how it can survive in liquid probiotics and if it is able to pass the stomach and cause infectious in humans, especially those immunosuppressed patients, who should take probiotics during their treatment. We do not have information about how P. aeruginosa behaves in probiotics. As we know Pseudomonas sp. have a great biofilm formation ability, it can be a high risk, if Pseudomonas s sp. is used in probiotics, especially if the consumer belongs to the YOPI group (young, old, pregnant, immunosuppressed).
